Sennheiser HD 560S

It already delivers amazing sound right out of the box with exceptional separation and clarity, but for my head, the cups are a bit too big. I can move them quite a bit to find the sweet spot but then I have a gap at my jaw which could alter the sound, especially bass. The clamping force is good but the plastic construction makes the headphones feel cheap. On the other hand, this construction makes it really light and comfortable in the long term.

Disclaimer: I've only had a few hours with these and am not a producer.

I use these headphones at home, powered by an iFi Zen Can, feeding it FLAC from my PC through a Digitech RP155 as a DAC. My favourite two hobbies at home are critical listening and video games, so that's my use for them. I also have Audio-Technica ATH-AD500X and a pair of IEMs.

Pros: very clear sound - they definitely give the impression of letting you hear everything in the music - to me they don't seem sibilant but they will cause listening fatigue at very high volumes quickly. I am very happy with the tuning of these cans - very revealing but not tiring and fun if you appreciate intricacies in sound.

Cons: build quality. Casing resonance from low frequencies at high volumes can be very obvious. This might be fixed eventually or never by Sennheiser.

Conclusion: I genuinely enjoy listening with these, the benefits to me outweigh the drawbacks and I consider these a legitimate upgrade to what I had before.
